SuperTux:
I'm sorry to inform everybody here of the news that The Amazing Race: China Rush has been canceled by ICS/Dragon TV.

But Shenzhen TV has bought the show and will produce a whole new season of The Amazing Race Chinese version.

News so far:Show content1) It'll be a celebrity version.2) It won't air until September at least. 3) The time slot is 0915pm, Sunday. 4) There're probably a lot of legs in which contestants have to drive by themselves, in view of the fact that the sponsor this time will be Infiniti. 5) Contestants will travel abroad. We're expecting five continents.

SuperTux:
Please don't expect too high for Shenzhen TV's version. As far as I know they'll probably make it look like a Korean show "Where's Dad" which focuses much more on relationships between the duo than on the competition itself--as it said, to reflect the quality of the duo themselves that they did not realize before they participate.
